General
Used for power users such as power plants, substations, factories
and mines, as AC 50-60Hz, rated working current up to 3150A in the
power distribution system, as the power conversion, distribution
and control of power, lighting and power distribution equipment.
The product has the characteristics of good dynamic and thermal
stability, novel and reasonable structure, practical electrical
scheme, strong serial usability, and high protection level. It can
be used as an updated product.
The selection of electrical components
A. The GGD cabinet mainly adopts the more advanced electrical
components that can be mass-produced in China, such as DW45, MCCB,
DZ20, DW15, etc. At the same time, it also retains some of the
usable components based on economic and reasonable principles and
under the premise of full consideration of feasibility. Old
products such as DZ10, etc., do not use obsolete electrical
components.
B. HD13BX and HS13BX rotary-operated knife switches are special
components designed by NLS to meet the needs of the unique
structure of the GGD cabinet. It changes the operation mode of the
mechanism and retains the advantages of the old products. It is a
practical new type of electrical component. .
C. If the design department selects new electrical components with
better performance and more advanced technology according to user
needs, because GGD has good installation flexibility, it will
generally not cause manufacturing and installation difficulties due
to the update of electrical components.
D. In order to further improve the dynamic stability of the main
circuit, NLS designed a ZMJ type combined bus clamp and insulating
support for the GGD cabinet. The busbar clamp is made of
high-strength, high flame-retardant PPO alloy material, with high
insulation strength, good self-extinguishing performance and unique
structure. It can be easily combined into a single busbar clamp or
a double busbar clamp by adjusting the building block. The
insulating support is a sleeve-type molded structure with low cost
and high strength, which solves the defect of insufficient creepage
distance of old products.
Features
1. According to the purpose, it is divided into: power receiving
cabinet, busbar connection cabinet, feeder cabinet, motor control
cabinet, reactive power compensation cabinet, lighting power
distribution cabinet.
2. Cabinet structure:
(1) The cabinet frame is partially welded and assembled with 8MF
cold-formed steel. The frame has mounting holes arranged according
to the modules of E=20mm and E=100mm to improve the versatility of
product assembly.
(2) The ZMJ type busbar clamp, which is thermoformed with high
flame-retardant PPO material, has a modular structure with high
mechanical strength and insulation.
(3) The 1000mm and 1200mm wide cabinets adopt a symmetrical
double-door structure on the front, and the 600mm and 800mm wide
cabinets adopt a whole door structure. The back of the cabinet
adopts a symmetrical double-door structure. The cabinet structure
is not installed against the wall.
(4) The cabinet door is connected to the frame with a galvanized
shaft hinge, which is convenient for installation and disassembly.
There are rubber inserts at the folding edge of the door.
(5) The grounding knurled screw structure is used between the
installation parts in the cabinet and the frame to form a complete
grounding protection circuit.
(6) The top cover of the cabinet body can be removed when needed to
facilitate the assembly and adjustment of the main bus.
